"... Elham Salah, head of the ministry’s Museums Department, told Ahram Online that the study is being carried out on a collection of 500 gold sheets found in a box in storage at the Egyptian Museum in Tahrir along with the remains of a skull and a handwritten note in French.

The note, she says, is dated to when KV55 was first found and states that the 500 accompanying sheets were discovered with a sarcophagus, though it does not mention which sarcophagus. ..."

I remember the DNA-TV-Show about Tutankhamens family, with Hawass looking at gold sheets from KV 55 searching a cartouche. But they were not stored in a box, he took them out of a kind maps cupboard (?).

"The Ministry of Antiquities is trying to decipher the most controversial mystery coffin in the history of ancient Egypt The Ministry of Antiquities resumes the study of the golden fragments found inside a wooden box inside the store of the Egyptian Museum in Tahrir with a grant of $28,500 provided by the American Research Center (ARCE) Endowment Fund 2016.

Elham Salah, Head of Museums Sector at the Ministry of Antiquities pointed out that the study will be conducted by a team of Egyptian archaeologists and restorers from the Egyptian Museum who would study another group of these fragments, which are likely belong to the sarcophagus of tomb KV 55 on the West Bank of Luxor.

Salah also explained that this study significantly contributes in resolving the controversy over the identity of the sarcophagus found in tomb KV55, considered as one of the most controversial sarcophagus in the ancient Egyptian history.

This sarcophagus is currently displayed in the Egyptian museum, she pointing out, and the studies conducted by the working team last year figured out the possibility of subordination of these fragments to the sarcophagus.

Islam Ezzat, member of the scientific office at the ministry of antiquities pointed out that after the completion of this extensive study the identity of the owner of this sarcophagus would be determined as well as the owner of tomb KV55. The researchers team is currently working on the dating of this sarcophagus through figuring out the similarities of these fragments with the sarcophagus and its inscriptions.

It is worth mentioning that the wooden box inside the museum’s store had about 500 golden fragments, a small part of a human skull, a paper written by hand in French dates to the time of the discovery of the tomb indicate that these fragments belong to a royal sarcophagus without specifying its name.

The researched team is working under the supervision of a large collection of Egyptian antiquities and restoration scientists in Egypt and the world including Prof. Faeza Hekal professor of Egyptology at the American University, Prof.Hassan Selim professor of Egyptology at Ain Shams University, Prof. Mark Gabold professor of ancient Egyptian language at the University of Montpellier in France, Prof. Arnest Brnikas professor of material science at the University of Heidelberg in Germany, Prof. Suseran Janescy Great Restorer in Boston Museum at the United States of America, and Hala Hassan, head of the first section of the Egyptian Museum."

"... One team of experts is to study the box of 500 gold fragments, and another team will work on a second set from the sarcophagus of tomb KV55, according to a statement published on the ministry’s official webpage on Wednesday, titled “Ministry of Antiquities is trying to decipher the most controversial mystery coffin in the history of ancient Egypt.” ..."

And here the current article ... I suspect to see as a kind of interim result of the investigation of the fund from 2015/2016. Particularly noteworthy is the assumption that the gold foils are not part of the coffin, but of the mummy from KV 55 ...

A box found in the funerary collection of Queen Hetep-Heres at the Egyptian Museum has led curators from a mystery to a new discovery

During restoration work carried out on Queen Hetep-Heres’s funerary collection at the Egyptian Museum in Tahrir Square in Cairo, a wooden box filled with a large number of pieces of gold foil was discovered as well as a detached piece of paper with the word Amenopete or Amenophis written on it. ...

... the story of this discovery went back to 2015 when curators at the Egyptian Museum had stumbled upon a wooden box within the storage area in the collection dedicated to Queen Hetep-Heres.

Upon opening the box, the curators discovered seven layers of 534 pieces of gold foil. The last layer contained a detached piece of paper with the word Amenophis or Amenopete written on it. ...

... Exploring the box, the team found pieces of wood and parts of a skeleton. Studies carried out on the foil had confirmed that it belonged to the Pharaoh Akhenaten as the name of the sun god Aten was engraved on some of the foil while other pieces bore Akhenaten’s titles such as “Ankh En Maat”, meaning “he who lived in life.” ...

... Selim told the Weekly that more study had shown that when the French had transported jewellery from Tanis to the museum more than 100 years ago they had restored all the collection but not the sarcophagus of Amenemuba which was in a very poor condition. The sarcophagus was put in the sarcophagi hall on the museum’s third floor and its gold foil was put inside a wooden box.

When the KV55 tomb was discovered, Selim continued, several sarcophagi were transferred to the museum, among them the one that may belong to Akhenaten. As the late restorer Ahmed Youssef was in charge of the conservation work of both the Amenemuba and Akhenaten sarcophagi, he put the gold foil of the Akhenaten sarcophagus on top of that of Amenemuba in the same box and separated each with a piece of paper.

Regretfully, Selim said, Youssef died before starting his restoration of both sarcophagi and nobody knew about the way he had divided the material apart from him. Both sets of foil will now be studied in order to restore them and insert them in their original places.

Selim said that the foil that belongs to Akhenaten was not from his sarcophagus, but it could once have been used to decorate the wrapping of his mummy. “From the shape and size of the foil it is almost impossible that it could have belonged to the sarcophagus,” Selim said, explaining that further study could confirm his suggestion. ...
